BENEDICT BEEHLER, OF ST. LOUIS, MISSOURI.

LUMBER-POLISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 231,259, dated August 1'7, 1880,

Application filed July '7, 1880. (No model.)

To all whom it may concern:

Be it known that I, BENEDICT BEEHLER, of St. Louis, State of Missouri, have invented a new and useful Improvement in Lumber-Polishing Machines, of which the following is a specification My invention relates to a machine which is more particularly intended for polishing thin lumber, such as is used for making cigar-boxes and for similar purposes.

The invention consists in a novel construction, arrangement, and combination of a stationary bed-plate and a tightly-journaled cylinder, whereby provision is made for simulta neously polishing both sides of the work as it passes through the machine.

In the accompanying drawings, Figure 1 rep resents a perspective view of a machine embodying my improvements. Fig. 2 is a vertical section of the same.

Similar letters of reference indicate corresponding parts.

The working parts of the machine are carried bya frame, A, ofan y suitable construction.

The machine is provided with feed-rollers B, similar to those employed in the ordinary lumber-planing machines, which rollers are driven by gearing from a shaft provided with a band-pulley, O.

The bed-plate E is curved in the form of an arc of a large circle, and its upper surface is smooth and polished.

Above the center of the bed-plate is journaled a cylinder, G, the surface of which is smooth and polished. The journals of this cylinder are fitted tightlyin their bearings, so as to prevent it from revolving under ordinary circumstances, and when the lumber is of the proper thickness and smoothness, but to allow it to revolve when the lumber is unusually rough or unusually thick, and thus prevent too great a strain on the machine.

The wood is passed through the machine and fed along by the feed-rollers B, in a similar manner to that in which the work is passed through a planing'machine. The polishing of both sidesof the work simultaneously is accomplished by the pressure and friction between the bed-plate E and cylinder Gr.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- In a lumber-polishing machine, the combination of a convex-surfaced bed-plate and a tightly-journaled cylinder, between which the lumber is passed and polished on both sides simultaneously, substantially as herein described.

BENEDIOT BEEHLER.
